Genes affected

TESMIN (HGNC:7446): (testis expressed metallothionein like protein) Metallothionein proteins are highly conserved low-molecular-weight cysteine-rich proteins that are induced by and bind to heavy metal ions and have no enzymatic activity. They may play a central role in the regulation of cell growth and differentiation and are involved in spermatogenesis. This gene encodes a metallothionein-like protein which has been shown to be expressed differentially in mouse testis and ovary. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Jun 11, 2021

The c.1508A>T (p.K503M) alteration is located in exon 10 (coding exon 9) of the TESMIN gene. This alteration results from a A to T substitution at nucleotide position 1508, causing the lysine (K) at amino acid position 503 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
